import { assertAlmostEquals } from "https://deno.land/std@0.145.0/testing/asserts.ts";
Make an assertion that actual
and expected
are almost equal numbers through
a given tolerance. It can be used to take into account IEEE-754 double-precision
floating-point representation limitations.
If the values are not almost equal then throw.
import { assertAlmostEquals, assertThrows } from "./asserts.ts";
assertAlmostEquals(0.1, 0.2);
// Using a custom tolerance value
assertAlmostEquals(0.1 + 0.2, 0.3, 1e-16);
assertThrows(() => assertAlmostEquals(0.1 + 0.2, 0.3, 1e-17));
